SPECIFICATION formingpart of Letters Patent No. 719,866, dated February 3, 1903. Application filed February 5, 1902. Serial No. 92,742. (No model.)

To @ZZ whom it may concern/.-

Be it known that LTHOMAS I. PORTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Seals, of which the following is a specification.

My invention relates particularly to an improvement in seals of the character described in my pending application, Serial No. 74,612, filed September 7, 1901.

My primary object is to provide against the possibility of surreptitiously removing the cord of the seal from its connection with the.

sealing-block and afterward restoring the connection Without the result being readily noticeable. i

- My improvement is illustrated in the preferred form in the accompanying drawings, in which- Figure l represents a perspective View of the improved seal afterthe'sealing-block has been subjected to the action of a press, the seal not being applied to any object, however; Fig. 2, a perspective view of the same, showing the reverse side; Figs. 3 and 4, sections taken as indicated at the corresponding lines of Fig. l; and Fig. 5, a longitudinal sectional view of the sealing-block corresponding with the section at Fig. 3, but taken before the sealing operation has been'performed.

The seal comprises a soft-metal sealingblock A, provided with a bag-piercing point a, and a tie-loop B, connected with the sealing-block. The tie-loop comprises a flexible tie-piece folded at its center and having its ends passing in a common direction through outer attaching-perforations Z) b', With which the block is provided, said ends being crossed at the opposite end of the block and returned through inner guide-perforations c c, located on opposite sides of the point a. Each strand of the tie -loop is by this construction connected with the block at an attaching-perforation at one longitudinal edge of the block and is returned through the guide-perforation which is farthest from its attaching-perforation.

In applying the seal to a bag the tie-loop is placed about the upper portion of the bag and the free ends of the strands are drawn upon to tighten the loop. Thereafter a sealing instrument is employed to transform the block from the dat form illustrated in Fig. 5 to the form illustrated in the preceding figures. The dies in the sealing implement are of suitable form to produce transverse struck-up portions d CZ on opposite sides of the longitudinal center line of the block, leaving an unbent portion cl2, forming a rib'ul3 between the recesses or hollows d4, the vstruck-u p portions themselves being separated by a relative depression ds. The result is to produce bends or curves in the strand-receivingperforations, as illustrated in Fig. 3, and to cause the walls of the perforations to bind upon or grip the strands. sealing implement with characters which are reproduced upon the block in such positions that they will aid in enabling detection if the seal is tampered with. The strand-receiving perforations being finally of tortuous form cannot readily be bored out to enable the strands to be reinserted in case the seal is tampered with. Moreover, the seal cannot be tampered with by cutting the lateral edges of the block and removing the strands through the channels thus provided and afterward restoring the strands Without the fraud being readily noticeable.

Changes in minor details of construction within the spirit of my invention may be made. Hence no undue limitation is to be understood from the foregoing detailed description.

What I claim as new, anddesire to secure by Letters Patent, is-

l. A seal comprising a soft-metal block having a central piercing point projecting from one end and longitudinal perforations flanking said point, and a tie-loop opposed to said stud and extending through said perforations, said block being struck up transversely to produce bends in said perforations, substantially as and for the purposes set forth.

2. A seal, comprising a softmetal block having two outer longitudinal attaching-per-A Itis usual to supply the dies of the forations and two intermediate guide-perforations, and a tie-loop comprising a flexible tie-piecehaving its two ends threaded through said outer perforations in a common direc- 5 tion, crossed and returned, respectively, each through the farthest guide opening, said block hzwing transverse struck-up portions producing bends in said tie-piece Within said block, substantially as described.
